CLASSIFICATION & LABELLING
Personal protection: face shield, chemical protection suit and particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered plastic containers. Wash away remainder with plenty of water.
According to UN GHS Criteria
Transportation UN Classification
UN Hazard Class: 8; UN Pack Group: III
Separated from oxidants, bases, metals and food and feedstuffs. Dry. Well closed. Ventilation along the floor.
Do not transport with food and feedstuffs.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance GREY-TO-YELLOW HYGROSCOPIC CRYSTALS OR FLAKES WITH PUNGENT ODOUR.
Chemical dangers Decomposes on heating. This produces toxic and corrosive fumes. The solution in water is a strong acid. It reacts violently with bases and is corrosive. Reacts violently with oxidants. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001).
